We’ve begun to investigate providing this feature and would like to hear more from those interested. Are you using call extensions already? If so, what percentage of your calls are over 5 minutes today based on the reports? If you aren’t using call extensions, is lack of this capability a blocker?

How are you using this feature on other platforms and how does it help with your search engine marketing optimizations?

I would love to see functionality that is similar to Google's call forwarding number conversion tracking. The code identifies a number on the landing page and swaps it out with a google forwarding number, sending the information back to google as a conversion when the forwarding number is dialed.
